.150. it known tflutt. l, 'iCrrA .ll. lt'ron, a eitizen oi the United States, residing at Worcester, in the county of Worcester and State of Massachusetts, have inveutul certain new and usefulimprovements in Looms, of which the. following is a specification.

My invention relates to looms, and more particularly to a shuttle box motion and shuttle changing mechanism for looms which have a plurality of drop or change shuttle boxes at each end, and by means of which the weaver may change a. shuttle, or substitute a shuttle having a. full supply of filling, for a shuttle having the iilling substantially or practically ex ltn-usted, whet lever he wishes.

1X1lit)"illlIJlOVClllUllizi, I employ a. particularly constructed cam box motion, and two additional shuttle boxes or cells at one end of the loom, which boxes or cells may be of any well. known constrtuation employed in shuttle clntnging looms. ()ne of said additional boxes or cells, as the upper box, is prei'erz'ibly for the spare shuttle, which is placed therein by the weaver, preparatory to changing a shuttle, and the other additional shuttle box or cell, as the lowest box, is preferably to receive the shuttle to be exclninged, the shuttle boxes or cells intermediate the upper and lowest. boxes are of the usual construction and operation.

1. have. only shown in the drawings detziched portions of a loom of the class referred to, having my improvements applied thereto, sullicient to enztb e those skilled in the art to understand the ctjmstruction and operation thereof.

The loom shown in the drawings is what is termed av two by two box loom, having at each end two shuttle boxes, and in this instance havin" on the tight hand end, two ad ditional sl-zzttle loxes, one above, and the other below the two ordinary shuttle boxes. '1. he upper box is in this instance for the spare shuttle, and the lowest box is for the shuttle to lie-exchanged.

Referring to the drmvings:l igure l is the right hand end view of portions of a. loom having my improvements in shuttle box motion and shuttle changing mechanism combined therewith; the shuttle box guide frame and shuttle boxes are shown in section. Fig. 2 shows, on an enlarged scale, some of the parts shown in. the upper part of Fig. 1, dctached, and in a different position. Fig. 3 is 5 5 at SCuliOll, on line 3, 3, Fig. 2, looking in the direction of arrow a, some figure. Fig. 4 corresponds to Fig. 2, butsome of the parts shown in Big. 2 are left oil, to show the parts in Fig. :2 which are concealed or covered by other parts.

in the accompanying drawings, 1 is the right hand loom side or end jl'rn-me; 2 are the ere-hes; 3 is the lay, 4 the lay-sword pivotally mounted at its lower end; 5 is the crank con- 6 nector to the crank shaft (5.

7 is the guide future on the end 01' the lay, for the drop or change shuttle boxes, which are mounted on the vertically moving rod 9. The drop or change shuttle boxes shown. consist in this instance of two ordinary shuttle boxes or cells 10, and an additional shuttle box or cell 11, located above the two shuttle boxes 10 for the spare shuttle, which is placed therein by the weaver, preparatory to chang- 7 5 ing shuttles, and a second additional shuttle box or shell 12, below the two ordinz'iry shuttle boxes 10, to receive the shuttle to be exchanged. 7 The shuttle box or cell 11, and the shuttle box or cell 12 may be of any ordinary construction employed iif'shiittle changing looms.

1 will now describe my improvements, which preferably relate to the shuttle box motion and shuttle changing meclnmism. 8 5

Secured to the end frame 1 is a stationary stud 13, on which is loosely mounted a gear -14, which is in mesh with and rotated by an intermediate gear 15, loose on a stud 16 fast on the end frame I and which is driven by a J pinion 17 fast on the crank shaft- 0. The gear 14 has securcdthcreto to revolve therewith, zt cam 19, the hub 19 of which is in this instance mounted on the extended hub 14 of the gear 14, see Fig. 3. 5 i

The cam 19 operates an angle lever 20, which carries an engaging lu 20, and is pivota-lly mounted on a stud 21, and is connected by a connector rod or link 22 with alever 23, which is pivotally mounted out one ICC end on a. stud 24, see Fig. l, and is connected at its other end to a Chitin 25 which passes over a sheave 26, and is connected to the drop or change shuttle boxes, not shown, at the other end of the loom, in this instance two x o in number, to raise and lower said shuttle boxes. The cam 19 also operates a second lever 27 which carries an engaging lug 27, and is pivotally mounted at one end on a stud 28, and is connected at its other end by a rod or connector 29 with one end of a lever 30, which is centrally fulcrumed or pivoted on the lower end of a connector rod 31, see Fig. 1. The other end of the lever 30 has attached thereto the lower end of the vertically moving box rod 9, carrying the shuttle boxes. The upper end of the connector 31 is connected to one end of a lever 32; the other end of said lever 32 is pivotally mounted on a stud 33 on the loom frame.

The up and down movement of the lever 32, through the rod 31, causes different pivotal or'fulcrum positions of the lever 30, and in combination with the movement of the lever 27, and through connector 29, the movement of the lever 30 and rod 9 causes the vertical movement of the shuttle boxes, to cause the additional box or cell 12 to be brought on a line with the race-way, to receive the shuttle to be exchanged, and then the additional box or cell 11 to be brought on a line with the race-way, -to have the spare shuttle therein picked, according to the movement of a second cam 34.

The cam 34 is secured to a second gear 35' which is loose on the stud 13. The hub 34", of the cam 34 is in this instance mounted on the extended hub 35 of the gear 35, see Fig.

3. The gear 35 is mutilated, or has some of its teeth removed, or left off, as shown in Fig. 4; said gear 35 is in vertical alinement with, and is operated, at the proper time, by the intermediate pinion 15, said pinion being of sullicient width to operate both gears 14, and 35, see Fig. 3.

The gear 35 is only operated by the pinion when the weaver indicates for the change of a shuttle, to bring the additional shuttle box or cell 12 in line with the race-way, to receive the shuttle to be exchanged, and then to bring the additional shuttle box or cell 11 in line with the race-way, to have the spare shuttle therein picked.

The indicating mechanism operated by the weaver, when an exchange of shuttles is desired, consists in this instance of a hand-operated lever 36, having its operating handle or end 36 at the front of the loom within easy reach of the weaver, and retained in its normal raised position by a helically coiled tension spring 37. The lever 36 is pivotally mounted at its rear end on the stud 33. ()n a stud 38 on the lever 36 is pivotally mounted the lever 39, of angular shape, and having an upright extension 39 thereon, which is notched or recessed at its upper end, and adapted to extend under and engage the pro- .jeeting end 40 on a stationary stand 40 secured to the loom frame, when the lever 36 is lowered sufficiently to allow the spring 41 attached to the extension 39 and to a lug 36 tudinally sliding bar 43, which is guided and held between the projections 35 on two up posi telv extending arms of the gear 35.

- -A helically coiled expansion spring 44-, held in place by a pin 45 on the bar 43, and a pin 46 on the hub 35, see Fig. 3, acts to return and yiel dingly hold the bar 43 in its normal position. The lower end 43 of the bar 43, when said bar is moved down by the hand lever 36, extends in the path of a knob or projection, shown by broken lines 47 in Fig. 2, on one arm of the gear 14, to cause, through the rotation of the gear 14 the retation of the gear 35, until said gear 35 meshes with and is driven by the gear 15. The teeth on the gear 15 and the teeth on the gear 35 are in alinement with each other at the time of the starting of the gear 35.

The rotation of the'gear 35 by the gear 15, will cause the rotation of the cam 34 with said gear 35, and the movement of the lever 32, and through connector 31, the raising .and lowering of the pivot or fulcrum pointof the lever 30, and at the same time the retation of the cam 19 will, through lever 27 and connector 29, move the lever and rod 9, to bring the additional shuttle box or cell 12 on a line with the race-way to receive the shuttle to be exchanged, and then, at the proper time, bring the additional shuttle box or cell 11 on a line with the race-way, for the spare shuttle to be picked. j

. As the gear rotates, the guiding projection 35 for the bar 43 on the arms of said gear, will engage the downwardly extending arm of the angle lever 39, see Fig. 4, and rock said angle lever on its pivot pin 38, to release the notched extension 39 from the holding Rrojection on the arm' 46, and allow the and-lever 36 to return to its normal raised position, the spring 44 having acted to move the slide bar 43 to its normal position and out of the path of the starting toothor projection 47 on the gear 14, when the. upper end of said bar 43 is moved out of engagement with the projection 36 on the lever 36.

In the rotation of the gear 35, the upper .end of the bar 43, after the hand-lever 36 has been raised as shown in Fig. 1, will pass under the lower c'am shaped end of the projection 36", on the lever 36, and engage the end of the horizontally extending arm of the angle lever 39, whiehwill extend in the path of said bar 43, as shown in Fig. 1, and the rotation of the gear 35 will be checked, and

said gear 35 ank the cam 34, and other parts will be locked or held, and remain in their stationary ino erative osition, as shown in Fig. 1, until he hand ever 36 is aga n operated.

It will be understood that the details of construction of my improvements may be varied if desired.

Having thus described my invention, what I claim as new and desire to secure by Lettors Patent is i 1.' In a loom of the class described, drop shuttle boxes having acell for a spare shuttie, and a cell to receive the shuttle to be exchanged, means to operate said shuttle boxes, and separate means, under manual control, connected to and operated by said first named means, to put out of action the spent shuttle, and put into action the spare shuttle.
